About the Scientific Calculator
A full scientific calculator with trigonometry, logarithms, powers, roots, constants and degree/radian modes.
How to use the Scientific Calculator
- Choose DEG or RAD for trigonometric functions.
- Use the number pad and function keys such as sin, cos, tan, ln, log, β and xΚΈ. Press 2nd for inverse functions and use Ο and e for constants.
- Press = for the result, DEL to delete a character and AC to clear.
When to use the Scientific Calculator
- Working with trigonometry, logarithms and powers in maths or science.
- Checking homework and exam practice answers.
- Quick calculations with brackets and constants such as Ο and e.
Common mistakes to avoid
- Leaving the calculator in the wrong angle mode (degrees or radians).
- Missing brackets, so that the order of operations gives a different result.
Tips
- Check the DEG/RAD setting before using trig functions. It is the most common cause of wrong answers.
- Use brackets to make the order of operations explicit.
